High-Resolution Infrared Study of PHD2: The P–H Stretching Bands ν1 and 2ν1

“…For the ν 1 band a path length of 280 mm and a pressure of 70 Pa were chosen, and the interferometer was equipped with a KBr beam splitter, an InSb detector, and a 2000-3000 cm −1 band-pass filter. In total 254 scans were coadded, and calibration done using CO 2 lines near 2350 cm −1 (9,10). We used also the Giessen peak-picking software package written by P. Jensen.…”

The (ν1, ν4, ν2+ν3, ν3+ν5) Polyad of D328SiF around 1600 cm−1, Studied by High-Resolution FTIR Spectroscopy

“…Calibration was done with H 2 O lines (10), which implies a scaling factor of 0.999 999 770 for the wavenumbers, as suggested in Ref. (11). Wavenumber precision is 1-2 × 10 −4 cm −1 .…”

High-Resolution Spectrum and Rovibrational Analysis of the ν2/ν5 Dyad of D3SiF near 700 cm−1

“…(7). No scaling factor was suggested in (8) for these calibration lines. The wavenumber precision is 1 ϫ 10 Ϫ4 cm Ϫ1 .…”
